A collaborative team of researchers from Shinshu University in Japan have found a new way to curb some of the potential dangers posed by lithium ion batteries. Repeated lithium deposition/dissolution during charge/discharge can cause serious accidents due to the deposition of lithium dendrites that penetrate the separator and induce internal short-circuiting. The researchers hope to solve the issues with a plating technology and eventually achieve a compact and high-capacity battery.
Researchers have developed a new way to improve lithium ion battery efficiency. Through the growth of a cubic crystal layer, the scientists have created a thin and dense connecting layer between the electrodes of the battery. "We believe that our approach having robustness against side reactions at the interface could possibly lead to the production of ideal ceramic separators with a thin and dense interface."
Using advanced computational methods, University of Wisconsin-Madison materials scientists have discovered new materials that could bring widespread commercial use of solid oxide fuel cells closer to reality.
A study of the unusual digestive system of an ancient group of insects has provided new insights into future biofuel production.
Cyanobacteria -- which propel the ocean engine and help sustain marine life -- can shift their color like chameleons to match different colored light across the world's seas, according to research by an international collaboration including the University of Warwick.
International solar thermal energy researchers have successfully tested CONTISOL, a solar reactor that runs on air, able to make any solar fuel like hydrogen and to run day or night - because it uses concentrated solar power (CSP) which can include thermal energy storage.
An analytical article based on the study of morphologic and chemical composition of particulate matter in motorcycle engine exhaust was published in the respected scientific journal Toxicology Reports. The group of authors was supervised by Aristidis Tsatsakis, a foreign member of the Russian Academy of Sciences and Doctor Honoris Causa of the Far Eastern Federal University, and Kirill Golokhvast, doctor of biology and Provost for Research at FEFU. The study was supported with a grant of the Russian Science Foundation.
Organic polymer solar cells show potential to provide solar power to remote microwatt sensors, wearable technology and the Wi-Fi-connected appliances constituting the 'internet of things.' While PSCs cannot match the durability or efficiency of inorganic solar cells, the potential to mass-produce nontoxic, disposable solar panels using roll-to-roll production makes them attractive for additional applications. In this week's Journal of Renewable and Sustainable Energy, researchers review the latest advances and remaining challenges in PSC technology.
The Innovative COmpound semiconductoR Laboratory team led by Professor Can Bayram, of the Department of Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign, has published a well-received paper titled 'High internal quantum efficiency ultraviolet emission from phase-transition cubic GaN integrated on nanopatterned Si(100).'
In an effort to create a power source for future implantable technologies, a team of researchers developed an electric eel-inspired device that produced 110 volts from gels filled with water, called hydrogels. Their results show potential for a soft power source to draw on a biological system's chemical energy. Anirvan Guha will present the research during the 62nd Biophysical Society Annual Meeting, Feb. 17-21.
